Mohan wants to donate a rectangular plot of land for a hospital in his village. When he was asked to give dimensions of the plot, he told that if its length (x) is decreased by 50 m and breadth (y) is increased by 50 m, then its area will remain same, but if length is decreased by 10 m and breadth is decreased by 20 m, then its area will decrease by 5300 m $^2$ .

The value $x$ is:

150 m

100 m

200 m

300 m

✅ Correct Option: 3

From the system $x - y = 50$ and $2x + y = 550$ .

Adding: $3x = 600 \Rightarrow x = 200$ m.
